Abstract

Debates about the concept of mental disorder involve social values, the medical model, and the sciences. It is generally agreed that the concept involves values, though how it does this continues to be disputed, and it is also recognized that the label of mental disorder or illness is stigmatizing. Wakefield's proposed definition of mental disorder in terms of harmful dysfunction locates the concept in an evolutionary theoretic framework. However, recent commentaries on Wakefield's analysis have suggested that research programs in evolutionary biology and psychology envisage a broader class of "treatable conditions" that may involve no dysfunction, and hence no disorder in this sense.
